Note: You may get a message indicating "all collectibles found" but not get the achievement. Ignore the message and check the tracker on screen to ensure everything is lit up including the van, letters, photos, and tapes. Once everything is found the achievement should pop as expected.

This video guide will help you locate all the collectables on the free roam level gimsoymyrene keeping in mind you have to unlock it first by finding all the collectables on Korkatti Lakes, San Pietro Islands & Kanto Mountains first.

Gimsoymyrene is the fourth free roam area available to play; you'll need to complete the collectibles on Kanto Mountains to unlock this area. Gimsoymyrene has 5 cassettes, 5 views, 5 RALLY letters, and a secret Van to collect. Collecting all of them will unlock the Mannebach free roam area.
